IN THIS PROJECT, WE PROPOSE TO DEVELOP ALL-PEROVSKITE TANDEM PHOTOELECTRODES (ACTIVE AREA OF 1 CM2) AND PANELS (ACTIVE AREA OF 25 CM2) TO ACHIEVE LOW-COST, HIGH STH (SOLAR-TO-HYDROGEN) EFFICIENCY (UP TO 18%) AND LONG-TERM STABLE (>500 HOURS) UNASSISTED PHOTOELECTROCHEMICAL (PEC) WATER SPLITTING SYSTEMS. THE OBJECTIVE FOR BUDGET PERIOD 1 IS TO DEMONSTRATE AN ALL-PEROVSKITE TANDEM PHOTOELECTRODE BASELINE FOR A SMALL-AREA DEVICE WITH AN ACTIVE AREA OF 0.1 CM2. THE OBJECTIVE FOR BUDGET PERIOD 2 IS TO DEVELOP SCALABLE PRODUCTION METHODS AND DEMONSTRATE LARGE-AREA ALL-PEROVSKITE TANDEM PHOTOELECTRODES WITH AN ACTIVE AREA OF 1 CM2. THE OBJECTIVE FOR BUDGET PERIOD 3 IS TO DEVELOP AND DEMONSTRATE ALL-PEROVSKITE TANDEM PHOTOELECTRODE PANELS WITH AN ACTIVE AREA OF 25 CM2 AND SHOW AN STH EFFICIENCY OF >18% AND RETAIN 80% OF THEIR INITIAL EFFICIENCY FOR MORE THAN 500 HOURS UNDER ONE SUN OPERATION.
